- Switch to noexamples tarball as requested in:
https://github.com/raysan5/raylib/issues/1180
So we don't ship examples with various licenses that we don't
install anyways.
- Add raylib-3.0.0-noexamples.patch: dont try to install examples
Raysan seems to have forgotten that.

- Added missing development header files.

- Update to 3.0.0:
* All global variables from the multiple raylib modules have
been moved to a global context state, it has several benefits, first, better
code readability with more comprehensive variables naming and categorization
(organized by types, i.e. CORE.Window.display.width,
CORE.Input.Keyboard.currentKeyState or RLGL.State.modelview). Second, it allows
better memory management to load global context state dynamically when required
(not at the moment), making it easy to implement a hot-reloading mechanism if
desired.
* All memory allocations on raylib and its dependencies now use
RL_MALLOC, RL_FREE and similar macros. Now users can easely hook their own
memory allocations mechanism if desired, having more control over memory
allocated internally by the library. Additionally, it makes it easier to port
the library to embedded devices where memory control is critical. For more info
check raylib issue #1074.
* All I/O file accesses from raylib are being moved
to memory data access, now all I/O file access is centralized into just four
functions: LoadFileData(), SaveFileData(), LoadFileText(), SaveFileText().
Users can just update those functions to any I/O file system. This change makes
it easier to integrate raylib with Virtual File Systems or custom I/O file
implementations.
